COKE-OVEN.

Spqi'lcation of Letters Patent Patented March 9, 1999.

A nmnn filed March 7, 1908. Serial No. sic lei.

To all whom it may concern:

381i known that I, Josnrn F. l')o.\',\o1n', a citizen of the United States, and a resident of Charleroi, in the'county of Washington and ovens and particularly in the means for closing the ends of the oven; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed. 1

n thedrawings Figure 1 is a front view of a coke oven embodying my invention. Fig. Z-is a vertical longitudinal section of one end thereof. Fig. 3 18 a. detail vertical section of one of the doors.- Fig.4 is a horizontal see- Fig. 5 is an elevation'of theouter side of one of the upper door tiles. 'Fig. 6 is a similar view-of one of the lower door tiles. Figs"? and 8 are sections on respectively the lines 7-7 and 8-8 of Fig. 6, and Fig. 9 is a detail plan view ofthe baseplate of-the door frame.

' In carrying out my invention I employ the upper doors A, the lower doors B and the frame for holding said doors comprising a base late C and a crown plate D having the sprig ts E and the ash F. and which may be made in sectionsbolted together at G, and flanged to facilitate such bolted connection as will be understood fromFigs. 1 and 2 of the drawing. B this flanged construction it will be noticed t at the arch isadapted to be adjusted by the insertion of filling plates between the flanges to enable the side plates to be moved fart-her apart whenever desired.

' in carrying out this construction the side plates have the inwardly projecting wings at theirupper ends which are connected to the arch bar as best shown in Fig. 1 of the drawing. It will also be noticed that the arch ban and the upright side plates do not fit within the opening in the end of the oven but are fitted fiat against the end of the oven and away from the opening, see Fi 1, so that the-v will. .be'protected from te heat. It will he noticed that the arch F is arranged 1 considerably above the arch H 'ofithe oven I and is shown as arranged sever'ii courses of hricla above the crown of' the arch H, and also considerably above the upper edges of e upper doors A, audit will be noticed that the upper edgesoithe'said ddorsAhthfcon siderably below the crown of the arch H of the coke oven, this construction being especially designed for coke oven purposes for several reasons. In the first place it is important to arrange the arch F as'high as practicable above the crown of the arch H in order to avoid as for as racticable the ovelalieating. of the arch i by the heatovhich may at times be discharged at the ends of the oven. A ain this relative arrangement of the arch permits the replacing of the bricks of the arch H at the ends of the even without displacing the door frame, and the location of the upper edges of the doors A below the crown of the arch F facilitates the filling in of the oven 0 ening at the crown of the arch by mud bric s and the like as is commonlypracticed, so such mud and brickmay be removed when desired in the operation of coking, as is well known to those skilled in such art.

The uprights E are provided at their lower ends with lugs E fitting in notches C in the plate C thus tying the uprights and said base plate together, and v the construction as shown forms a rigid door frame braced at top .and bottom so the weight of the doors cannot cause them to sag in the use of the invention, it being understood that the said doors are quiteheavy and requires. particularly strong frame to prevent suchsagging as the doors are used, especially under the influence of heat.

The door frames are bolted at J securely to the brick work of the oven and operate not only to supportthe doors but also in a measure to brace the masonry of the oven v. hen applied thereto, shown in F igs'. l and 2, it bein understood that similar doors areprovidel at the opposite ends of the oven.

The invention may be applied to the long coke ovens v ith doors at each end, but can also be used on the'bee-hive ovens as well. It is not necessary for the bolts J to extend through the even as it is only essential to have said bolts anchored in far enough to secure the door frame solidly in place.

The doors A and B are preferably lined, with tiles K and L of fire ch or other refractory material, and the said core are made in the form of open frames as shoun at A and B in order. to permit the air to have access to the tiles to prevent the same from overheating, the doors being recessed on their inner faces at A and G to receive the tiles is. and

, and facilitates such. operation of luting in an L, and the tiles K and L are rabbeted at K and L forming flange like portions w ich overlap the doors and protect the same as best shown in Figs. 3 and 4 of the drawings. The edges of the tile taper and converge toward each othertoward the outer face of the tile as best shown in Fig. 2 when the doors are closed and this is an important feature as it affords a tapering seat for the clay in luting the joints between the doors and thus prevents the forcing of the clay into the oven eliectual manner as wili be understood from Fi s. 1 and 2 of the drawings.

in Fig. 4 1 illustrate a clamping band M encircling the tile and clamping the edges thereof in such manner as to aid in preventing craeki of the tile under the influence of heat ariil also holding the ire ments of the tile .should it become cracks In securing the tile to the doors I employ bolts N having heads N at their inner ends seated in sockets K and L in the inner faces of the tile and communicating with the bolt holes through which the shanks of the bolts extend, the outer ends of the bolts being secured by keys N as shown in Figs. 3 and 4. The heads N seat against asbestos washers 0 and asbestos paste 0 is a plied over the heads N after which'a fire c ay or other refractory plastic 0 is applied over the asbestoe paste as best shown in Figs, 3 and t, thus protecting the heads of the bolts from injury 3/ the fire in the oven.

It n ill be noticed from Figs. 5, and 6 that the bolt openings in the tiles K are-elongated, such construct-ion )ermitting anadjustment of the tiles v. ithin t ieir supporting frames and in such manner as to secure the desired accurate fitting in the use of the invention.

The doors A and B are hinged by the intles P and I to the door frame. It wil be noticed from Fig. 1, that these piutles P and while the general inclination 'of the doors is inward toward their upper ends, the axes of the hinges of the up or doors approach the vertical, this being est shown in Fig. 2.

This enables the arrangement of the upper I doors at an inclination and facilitates the opening of said doors b swinging themon an axis at an angle less t an that of the door and approaching the vertical as distinguished from an inclined axis so the doors may be easily opened, this arrangement of the hinges of the upper doors being es ecially advantageou's, because, the said (oors being arranged so high, would be very diiiicult to open shouldt incline.

e hinges be at any considerable In 0 eration it will be understood that.

after t e oven is charged and the'doors closed, the opening between the u per edges of the top doors and the crown o' the oven arch, may be filled in as usual the doors supporting such filling H when the latter is ap-fl'.

plied as shown in Fig. 2 of the drawings.

The doors are provided near their swinging edges with depending stop "plates R and adjacent thereto;with 0 latter may be engaged the doors.

I claim:

or? or staples S which y hooks in opening f so 1. In a door'mechanism for coke ovens, the combination with the frame of u per and lower door's hinged thereto, the pint es of the i latter may be removed and replaced without interfering with the arch plate of the door frame, upper and lower doors and hinges securing the same tothe door frame, the pin tles of the upperhinges being arranged more nearly vertical than the door frame to iacilitats the opening of said doors, substantiaily as set forth. g
